This treatment is called peritoneal dialysis (PD) because the filtering of the blood is done in the peritoneum - the membrane that lines the cavity.
The peritoneal cavity acts as a storage area for the dialysis fluid and the filtration takes place across the peritoneum. Toxins and excess fluid cross the peritoneal membrane during the pre-scribed dwell time.
A permanent tube or catheter, is inserted into the peritoneal cavity. Through which, dialysis fluid is fed into the cavity and left to absorb the impurities from the blood. Later, the fluid is drained-off into a bag and replaced with fresh fluid. This process of filling and draining, can be done manually during the day (Continuous Ambulatory Peritoneal Dialysis, CAPD) or using an automatic process at night with a cycler (Automated Peritoneal Dialysis, APD). Either way you will need to feel capable and confident to handle the procedure.
Who is Peritoneal Dialysis right for?
There are times when peritoneal dialysis may be the better option. But in many cases, it’s a medically-driven choice. For example, if you have some types of heart or vascular disease. Because of their restricted vascular access, peritoneal dialysis is usually the treatment choice for young children. Opting for dialysis at home also allows children to continue their schooling.
